I'm trying to do a small function (see below) and keep getting an
error message which
I can't solve via examples.
I want to look back and check a number of conditions which give bad
screenings.
There is only one in my problem below.
I get error 6 expression must be numeric or Boolean. I tried
different work arounds but
Can't get it right.
I guess I would appreciate someone pointing out the error of my
ways. I put comments on the line that get an error message.
Thanks

function NoJumpingUp( lookback )
// this program tests if a stock has made a significat jump.
// if it has made such a jump, the technical analysis is not valid.
// daysback = howfar back to look for jumps
// percnt = a percentage of Average True Range
// ATRange = parameter of ATR function i.e. ATR(ATRange)
// typically I use the values 15, 10 & 7 for the parameters
{
gotone = 0;
keyset = 0;
Lowtoday = 0;
Hiyesterday = 0;
Lookback = (-1) * abs(lookback);
for( i = 0; i > Lookback; i-- )
{
k = i-1;
Lowtoday = Ref(Low,i);
Hiyesterday = Ref(High,(i-1));
// if ( Ref(Low,i) < Ref(High,k) ) ///--- Does NOT WORK
if ( Lowtoday < Hiyesterday ) /// ALSO does not work!!!!!!!
{
Null;
}
else
{
keyset = 1;
}
}
return keyset;
}
nojumpupt = nojumpingup(15);
Thanks,
